the truck has had troubles running at startup... it would slowly die at points...
after investigating, I found my fuel system was leaking and losing pressure. it was letting air in But hard to tell where. I would build pressure using the hand pump on the fuel filter, but after a minute it would lose pressure.
I proceeded to re build my pre filter system (racor 500fg) with all new seals and a new drain plug. I lso replaced all of the rubber fuel hoses and clamps. A new OEM fuel filter was swapped in as well... but...
after reassembling I found that the low level sensor at the bottom of the OEM filter was leaking... so I have a new sensor inbound.
